Module: CROUTE-MIB

OID (symbolic): CROUTE-MIB::drStaticCidrTos

OID (numeric): 1.3.6.1.4.1.81.31.7.1.1.4

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: Equivalent  to ipCidrRouteTos.
The policy specifier is the IP TOS Field.  The encoding
of IP TOS is as specified  by  the  following convention.
Zero indicates the default path if no more  specific
policy applies.

What is drStaticCidrTos?

This field is the Type-of-Service policy specifier for a static CIDR route, equivalent to ipCidrRouteTos, allowing a route to be selected based on IP TOS or precedence bits rather than destination alone, with zero meaning the default path applies when no more specific TOS policy matches. Network admins use this in policy-based routing scenarios where traffic needs to be steered differently depending on its precedence or service-type marking. For example, a route with a non-zero drStaticCidrTos value could send high-precedence voice traffic over a different path than the default-TOS route to the same destination.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.81.31.7.1.1.4
snmpwalk -v2c -c public <target> CROUTE-MIB::drStaticCidrTos

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.81.31.7.1.1.4.1
snmpget -v2c -c public <target> CROUTE-MIB::drStaticCidrTos.1

Create custom SNMP monitor using the CROUTE-MIB::drStaticCidrTos OID value, configure state conditions and alerts, and monitor any Layer 3 switch platform (vendor unclear, BOOTP/RIP) from a single console.
